Mike Zoeller and Adam Mosbrucker play key roles within the United States Geological Survey (USGS) Volcano Hazards Program. Both Mike and Adam rely heavily on the use of lidar and its derivative products to support applied science projects related to the specific volcanology of their respective regions, the Hawaiian Volcano Observatory (HVO) and the Cascades Volcano Observatory (CVO), respectively. In this episode, we chat about some of the exciting and novel applications of lidar within their work such as locating landing zones for helicopters and finding ideal placement locations for telemetry and solar power systems for GNSS instrumentation. We also discuss how lidar is utilized to constrain lava flow, develop geophysical models of underlying volcanic mechanics and get a handle on long-term sediment storage and basin yields.

The substantial achievements of UAV-lidar integrators have featured frequently in LIDAR Magazine’s articles and posted press releases. Dr. Tristan Allouis, co-founder and CEO of YellowScan, based in beautiful Montpellier, France, talks about why he started the company in 2012, only a year after completing his PhD. He explains the YellowScan product lines and is particularly proud of the in-house development of the Navigator system, which uses YellowScan’s own topobathymetric lidar sensor. With the arrival of Navigator, YellowScan is not just an integrator, but a manufacturer too. Tristan emphasizes YellowScan’s focus on service and explains how a company with roots in the magic of France competes effectively in the global UAV-lidar market-place.

Many of us have marveled at NASA’s spaceborne lidar systems, ICESat-2 and GEDI. The technical challenges of detecting returning photons and generating accurate elevation data are considerable. An Orlando start-up, NUVIEW, is planning a constellation of 21 lidar smallsats, each about the size of a dishwasher. The first one, “Mr. Spock” or space proof of concept, is in an advanced stage of preparation. In this episode, Clint Graumann, CEO and co-founder of NUVIEW, answers our questions about the company, its technology and proposed constellation, the leadership and the business aspects. NUVIEW emerged from stealth mode in 2023 and counts award-winning actor Leonardo DiCaprio among its investors. NUVIEW has fomented considerable excitement in the geospatial world and has already won several awards.

Katreen Wikstrom-Jones and Jill Nicolazzo work at the Alaska Department of Natural Resources: Division of Geological and Geophysical Surveys (DGGS). Within the geohazards department, they utilize field measurements, remotely sensed data products, and numerical models to glean a better understanding of climate and cryosphere hazards.  In this episode, we chat about how the team utilizes airborne lidar data to study landslides and avalanches and how these events affect humans and critical infrastructure within the State of Alaska. We also discuss what it’s like to undertake fieldwork up north (hint: bears)!

In this episode, we introduce Austin Madson, associate editor of LIDAR Magazine and co-host of the podcast. An Earth scientist by trade, Austin has research interests that intersect the hydrosphere, cryosphere, biosphere, and lithosphere. Currently a professor at the University of Wyoming School of Computing, we discuss how he became involved with geospatial technology. We also address his drone lidar venture, Mad Nadir Mapping.

McKim & Creed is an engineering and surveying firm with 24 offices in the southeastern US. In this episode, Matt LaLuzerne, National Director of BD & Geospatial Services, and Ravi Soneja, UAS Program Manager, talk about their careers and why they joined McKim & Creed. We discuss the firm’s characteristics, capabilities and approach to project management. The conversation broadens to consider the evolution of the industry and how it has been influenced by the high cost of sensors mounted in crewed aircraft and the arrival of highly performant UAV-photogrammetry and UAV-lidar systems.

In this episode, Dr. Austin Madson interviews Chris Crosby, the co-principal investigator and director of operations and strategy for the OpenTopography project. OpenTopography facilitates efficient access to topographic data, tools, and resources to advance our understanding of the Earth’s surface, vegetation, and the built environment. Funded by the National Science Foundation, it’s arguably the most comprehensive source of topographic data on the internet. During our session, we review the different resources available at OpenTopography.org (and who can/can’t access them) as well as the varied landscape of modern topographic data access and management.

The Open Geospatial Consortium (OGC) is perhaps the best-known standards body in the lidar world. In this episode, Chief Standards Officer Scott Simmons describes the organization, its structure and processes. We also discuss lidar, especially OGC’s work with the LAS and LAZ lidar data formats and the efforts of its Point Cloud Domain Working Group. Our discussion delves further into OGC’s interactions with other standards bodies, such as the International Standards Organisation (ISO) and buildingsSMART International. We close with a review of OGC’s changing membership and its future directions.

Ron Roth, Product Manager Airborne Topographic Lidar, Leica Geosystems, part of Hexagon talks about his life in lidar since the mid-1990s and about the evolution of Leica Geosystems’ airborne topographic lidar product line, of which the latest model is Leica TerrainMapper-3. He explains the trend to hybrid airborne systems that capture both imagery and lidar. He also touches on the topobathymetric, bathymetric and single-photon lidar parts of the portfolio.

Ron Chapple has devoted his amazing career to flying helicopters, first for cinematography, but then to acquire imagery and lidar for geospatial purposes. His work has won multiple awards, including a Pulitzer prize, and has been instrumental in the discovery of archaeological wonders in Latin America. His company, GEO1, was acquired by US geospatial services giant, NV5 Geospatial, in 2022 and Ron now serves as Vice President Global Strategic Solutions - Digital Twins, NV5 Geospatial. In the podcast Ron discusses his life in flying, his transition to geospatial, the acquisition by NV5 Geospatial, and the creation of and data acquisition for digital twins.
